But as far as I know, cameras tend to go down in price after the initial selling spree. And, as far as I know the Sigma cameras tends to go down in price quite early. Its a matter of market forces in play. When the first initial buyers start to thin out, then (if the stores and/or factory have more in stock) the price tends to go down.

Where I live, in Sweden, its more stable. We seldom see the price drops here, for some reasons.

So, if I want to buy e.g. a cheap Pentax K01 (which has dropped LOW in price), I have to buy it from somewhere else. In Sweden it is almost the same price as when it was released.

BTW - the reason for the K01 drop is that it sold very badly. Its discussed in the Pentax SLR forum. Go figure.
